VENTILATOR;

SPECIFICATION forming part of Letters Patent No. 542,501, dated July 9,1895.

Application filed February 28, 1895. Serial No. 540,050- (No model.)

To all whom it may concern.-

Be it known that I, WILLIAM W. ROBINSON, a citizen of the United States,and aresident of Ripon, in the county of Fond du Lac and State ofWisconsin, have invented certain new and useful Improvements inVentilators; and I do hereby declare that the following is a full,clear, and exact description of the invention, which will enable othersskilled in the art to which it appertains to make and use the same,reference being had to the accompanying drawings, which form a part ofthis specification.

My invention relates to window-ventilators for railway-cars and housesand buildings of all classes and descriptions; but it is moreparticularly adapted for use in connection with railway-cars, and itsobject is to provide an improved device for such purpose which shallpossess superior advantages with respect to efficiency in operation.

The invention consists in the novel construction and combination ofparts hereinafter fully described and claimed.

In the accompanying drawings, Figure 1 is a perspective view ofawindow-sash, showing my improvements applied thereto, looking from theoutside. Fig. 2 is a similar view looking from the inside. Fig. 3 is atransverse section of the lower part of the sash.

In the said drawings the reference-numeral 1 designates the side railsof a railway-carwindow sash, 2 the top rail, and 3 the bottom rail,forming a rectangular sash adapted to engage with the window of a car. Ashort distance above the bottom rail is longitudinal rail 4, extendingfrom acro the sash and secured to the sides thereof, and provided at itscenter with a vertical rail 5, secured thereto and to the bottom rail 8,forming two rectangular openings, which are closed by means of doors 6,hinged at their lower edges to said lower-rail and provided at theirupper ends with pivoted latches 7, adapted to engage with keepers orcatches 8 on the intermediate longitudinal rail. On the outside of thesash is secured at strip of wire-gauze 9, which serves to prevent dustor dirt from entering said openings. On the outside of the sash is alsosecured a hood 10, of metal or other suitable material, comprising theinclined ends 12, bent at an angle to the body portion, horizontal top13, and the flanges 14:, by which the hood is secured to the sash byscrews 15 or other fastening devices. It will thus be seen that a hoodor housing is formed closed at the top and open at the bottom.

In operation the air will enter through the open side of the hood andpass through the wire-gauze screen, which will exclude dust, dirt, andcinders. From thence the air will pass through the openings, the doorsbeing While the invention, as before stated, 's more especially adaptedfor railway-cars,,it may be used with equal advantage in schools,factories, dwelling-houses, and other bnildings.

Havingthus described my invention, what I claim is- The combination witha window sash pro- [Mided with a horizontal rail and a verticalrail--near the lower end, of the hinged doors, the wire gauze screen andthe hood or housingsecured to the outside'of the sash, open at the lowerside and closed at the upper side, substantially as described.

In testimony that I claim the foregoing as my own I have hereuntoaffixed my signature in presence of two witnesses.
